Background
As part of security requirements - to avoid leaving traces of very sensitive data in memory, we are trying to clear memory as much as it is possible. All instance of java.lang.String are immutable and stay in memory until Garbage Collector deletes them.
Solution
Avoid needlessly calling .toString() if the value already is a CharSequence
